False signal suppression
Change now?
Proceed as follows:
1. Move from the measured value display to the main menu by
pushing [OK].
2. Select the menu item "Service" with [->] and confirm with [OK].
Now the menu item "False signal suppression" is displayed.
3. Confirm "False signal suppression - Change now" with [OK] and
select in the below menu "Create new". Enter the actual distance
from the sensor to the product surface. All false signals in this
area are detected by the sensor and saved after confirming with
[OK].
Note:
Check the distance to the product surface, because if an incorrect
(too large) value is entered, the existing level will be saved as a false
signal. The level would then no longer be detectable in this area.
The menu item "Extended setting" offers the possibility to optimise
VEGAPULS 63 for applications in which the level changes very
quickly. To do this, select the function "Quick level change > 1 m/min.".
Extended setting
quick level change > 1 m/min.
Note:
Since with the function "Quick level change > 1 m/min." the genera-
tion of an average value of the signal processing is considerably
reduced, false reflections by agitators or vessel installations can
cause measured value fluctuations. A false echo memory is thus
recommended.
Profibus transmits two values cyclically. The first value is determined
in the menu item "Channel". The selection of the additional cyclical
value is made in the menu item "Additional PA value".
The following values are available with radar, guided microwave and
ultrasonic sensors:
•
SV1 (Secondary Value 1): Percentage value after the adjustment
•
SV2 (Secondary Value 2): Distance value before the adjustment
•
PV (Primary Value): Linearised percentage value
With pressure transmitters the following values are available:
•
SV1 (Secondary Value 1): Pressure or height value before adjust-
ment
•
SV2 (Secondary Value 2): Percentage value after the adjustment
•
PV (Primary Value): Linearised percentage value
